Suppose you want to restore the binary log of the employees database on a production server as employees_dev on a development server. You can use the --rewrite-db='from_name->to_name' option. This will rewrite all occurrences of from_name to to_name.
To convert multiple databases, specify the option multiple times:
shell> sudo mysqlbinlog /data/mysql/binlogs/server1.000001 --start-position=1499 --stop-position=1646 --rewrite-db='employees->employees_dev'~# at 1499#170815 13:29:27 server id 200 end_log_pos 1646 CRC32 0xc73d68fb Query thread_id=8 exec_time=0 error_code=0use `employees_dev`/*!*/;~~UPDATE salaries SET salary=salary*2 WHERE emp_no<10002/*!*/;SET @@SESSION.GTID_NEXT= 'AUTOMATIC' /* added by mysqlbinlog ...
